SOURce[1]:AMPlitude

Set

Query

Description

Sets the output amplitude for the

SOURce[1]:FUNCtion command. The query

command returns the current amplitude settings.

Note

The maximum and minimum amplitude depends

on the output termination. The default amplitude

for all functions is 100 mVpp (50Ω).

The offset and amplitude are related by the

following equation.

|Voffset| < Vmax – Vpp/2

The output amplitude can be affected by the

function and unit chosen. Vpp and Vrms or dBm

values may have different maximum values due to

differences such as crest factor. For example, a

5Vrms square wave will be adjusted to 3.536 Vrms

for a sine wave.

The amplitude units can be explicitly used each

time the SOURce[1]:AMPlitude command is used.

Alternatively, the VOLT:UNIT command can be

used to set the amplitude units for all commands.

Syntax

SOURce[1]:AMPlitude {< amplitude>

|MINimum|MAXimum}

Example

SOUR1:AMP MAX

Sets the amplitude to the maximum for the current

mode.

Query Syntax

SOURce[1]:AMPlitude? {MINimum|MAXimum}

Return Parameter

<NR3>

Returns the amplitude for the current

mode.
